One of my programmers brought an error to me that I need to get some clarification on ...
Its says:
The total row size (24301) for table xxxx eceeds the max number of bytes per row(8060). Rows that exceed the max number of bytes will not be added.

0 Bytes
Dec 26, 2001Hi,
I used to write the data in a database throught the component. Few days it worked fine and suddenly one day it showed the database is suspect and the file size is 0 bytes but actually is should have written lots of data.
But i have the datafile which shows zero bytes and when i try to attach it it gives an error:
Server: Msg 823, Level 24, State 6, Line 1
I/O error 38(Reached the end of the file.) detected during read at offset 0000000000000000 in file 'D:EorderdatabasePritamdbeorderpritamdb_Data.mdf'.
Connection Broken
Can anyone tell y is this. And it would be really if anyone can tell how to recover the data. The only thing which i have now is the data file which shows zero bytes.
Thanks.
WTF.. Bytes Per Row???
Aug 24, 2005I tried to ALTER TABLE calendar NOCHECK CONSTRAINT ALL and I got this error:
Warning: The table 'messages' has been created but its maximum row size (8321) exceeds the maximum number of bytes per row (8060). INSERT or UPDATE of a row in this table will fail if the resulting row length exceeds 8060 bytes.
I'm not too certain what this error means so I manually deleted the records in this table. I got the same error.
Memory Available Bytes
May 30, 2008I'm taking a look at a server to optimize it and need a better understanding of the Memory Available Bytes.
If the graph is showing this @ 100 is that a good or bad thing.
Articles are saying it shouldn't be below 4MB...
Can anyone elaborate?
thanks,

Eventually I need to only get the first 50 bytes of the data field, but somehow, I use len('==data==',50), it would catch 50 chinese characters which make 100 bytes ...
can anyone help me?
Thank you very much no matter what the result is ;)
Converting Bytes To String
May 3, 2007Hi guys,I'm currently trying to insert image into my SQL db.
I have tried a number of methods that were posted online, and so far
with no luck.My current code reads: Dim conn As New Data.SqlClient.SqlConnection() conn.ConnectionString = ConfigurationManager.ConnectionStrings("MainDBConnection").ToString conn.Open() Dim cmd As New Data.SqlClient.SqlCommand("SP_SAVEImage", conn) cmd.CommandType = Data.CommandType.StoredProcedure Dim sImageName As New Data.SqlClient.SqlParameter("@sImageName", Data.SqlDbType.VarChar, 50) sImageName.Value = sImageName Dim sImageType As New Data.SqlClient.SqlParameter("@sImageType", Data.SqlDbType.VarChar, 50) sImageType.Value = fileType Dim sImageData As New Data.SqlClient.SqlParameter("@sImageData", Data.SqlDbType.Image, uploadedFile.Length) sImageData.Value = uploadedFile cmd.Parameters.Add(sImageName) cmd.Parameters.Add(sImageType) cmd.Parameters.Add(sImageData) Dim reader1 As Data.SqlClient.SqlDataReader reader1 = cmd.ExecuteReaderRunning
through debug, everything runs up until the last line, where an error
is caught saying : Failed to convert parameter value from a
SqlParameter to a String I reckon it's to do with the input sImageData being input as a byte array - but I can't seem to find a way around it. Any help greatly appreciated!!
Maximum Number Of Bytes Per Row
Aug 1, 2001if SQL SERVER 2000 only allow 8060 bytes per row, then how can it store images or CLOB data? Is there a way that would let us change the maximum number of bytes per row? Any help would be greatly appreciated. Thanks.

Calculating Number Of Bytes
Jun 7, 2004Hi,
We are trying to get a rough estimate of the size of the warehouse in terms of number of bytes. Now I understand that when I say char(2) datatype requires 2 bytes of memory. If this is correct then how many bytes does the following data type need -
1. smalldatetime
2. decimal(14,2)
3. decimal(12,2)
4. int
5. smallint.
6. decimal(9,0)
Also can you explain the byte allocation for a varchar column. Say varchar(20) for example.
Any help is appreciated.

View 3 Replies View RelatedImage Limitation Of 510 Bytes
Feb 22, 2007Hello,
I have a field in my SQL Server 2000 with type "varbinary(8000)" which I merge onto my SQL CE 2.0 database. On my SQL CE 2.0, this field becomes "image".
Based on Microsoft's site: http://msdn2.microsoft.com/en-us/library/aa257477(SQL.80).aspx, "image" is used if the size is not over 510; however, when I populate this field in SQL CE, the maximum size that is stored is 510 bytes. I have verified my source data was complete (2622 butes) when again when I check the size of the field after an insert, it had only 510 bytes.
What's the work-around?
Thank you.
How Do I Calculate Current Total Bytes Per Row Used
Feb 16, 2001We are close to exceeding the Maximum Row size of 8K per row and the CIO asked me "how close are we to reaching the 8K row limit?"
I began by looking at byte requirements for the data types we are using
from the systypes table then I wondered, do the indecie, Foreign Keys and Primary Keys use bytes which must be included in my Calculation for current number of bytes used per Row.
Question: How do I calculate Current total number of bytes used per row.
Convert Image Column's Bytes To Int's
May 14, 2008Hi I have an image column (Spectrum) in a Table (ParticleEDS) which is populated with an array of a bunch of INT32's (4 bytes each)
Using TSQL is there any way that I can read each 4 bytes (convert this to an INT) and return this data for a given record (based on ParticleEDSID).
I know that there are 8192 byes (2048x4 bytes) that make up the image column.
I would like the output of the query/stored procedure to be:
Value
------------
1 2342
2 2334
3 3343
.....
2048 1001
I am thinking that the way to do this would be to convert every 4 bytes into an int and create a temporaty table with an integer column which I populate with int and then run a select * on this temporary table.
Does anybody have any pointers on how I can start to do this?

Limit Of 8060 Bytes Per Table Row
Sep 30, 2015I thought I understand the notion in the Title until I ran the query below. This query inserts a 5000 byte value into two columns in the same record and sql (2008) doesn't complain.
-- drop table table_1
create table table_1(
[mychar1] [varchar](8000) NULL,
[mychar2] [varchar](8000) NULL
)
insert into table_1 ( mychar1, mychar2)
values (replicate('a', 5000) , replicate('b', 5000))
select * from table_1
-- truncate table table_1
I just noticed that using Replicate ('a', 50000) doesn't cause an issue either. I'll be reviewing the replicate documentation too.
Log Sent Rate Is Low As Compared To Log Bytes Flushed/sec
Jun 12, 2007Hi,
We have Asynchronous Database Mirroring on SQL Server 2005 SP2 Entprise Edition/Windows 2000 Advanced Server. We noticed that log sent rate is quite low (average 1.3 MB/sec) in most of the cases whereas "Log bytes flushed/sec" is high (1.4 MB/sec) as a result Log send queue keeps on increasing and finally taking all the transaction log space. Our disk queue length is always in range of 0.01. And prinicipal and mirror servers are on local LAN.
I tried on low end server and high end server and in both cases Log sent rate is approx 1.3 MB/sec (Maximum 4 MB/sec).
Is there any limitation on Log sent rate?
How can we improve on log sent rate? Since both servers are on local LAN, network bandwith does not seems to be an issue.
Any help is greatly appreciated.
Thanks,
Ramesh
How To Guarantee Unique Of Columns &&> 900 Bytes
Aug 14, 2006We have an app that threads together emails coming out of Exchange, using their messageid. To ensure threading works correctly, we need to ensure uniqueness of messageid, which we do with a unique index (we also need to be able to lookup by messageid when a message comes in).
We are currently porting the app from Oracle and PostgreSQL to SQL Server and are having problems with the 900 byte max length of an index. The problem is that the maximum size of a messageid (according to the Exchange docs) is 1877 bytes.
How can we guarantee uniqueness?
SMALLINT: VALUE: 12 OR 12000 WHAT WILL THE ACTUAL SIZE: 2 BYTES OR ?

I want to know that
If it contains like 0 or 100 or 1000 or -200 or -2000 or more or less.
What will its actual size?
2 bytes or change with the value.

Dividing Bytes By 1 Million To Get Megabytes In Select
Feb 13, 2005Hello!
I have a table that contains a field containing the total bytes for a file. I am displaying the information in a datagrid but need to display the information in MB. If I divide by 1,000,000 in my select statement as such:SELECT cs_fileSize / 1000000 AS MB, cs_fileSize
FROM t_client_spotsI get the following results:
MB | cs_filesize
1 | 1899602
1 | 1782281
I would like the results to be:
MB | cs_filesize
1.89 | 1899602
1.78 | 1782281
Any suggestions?
Thanks in advance!!

SQL Rows In Pages Exceeding 8060 Bytes
Jan 14, 2008This is a question that I have not had an opportunity to test. Was wanting to know if anyone in the SQl world knows the answer. In SQL 2K and 2005 your rolls are limited to 8060 bytes without using varchar(MAX). My question is do you have to specify varchar(max) before your roll can exceed 8060 or does SQL 2005 exceed without specifing varchar(Max). Also does SQL 2005 expand it across multiple pages automatically. Please assist if you can.
Thanks
Error: Exceeded Maximum Number Of Bytes Per Row
Jan 23, 2008Hello, I received an error while attempting to create a table similar to the following...

[FIELD_25] [nvarchar](255) NULL,
[FIELD_26] [nvarchar](255) NULL,
[FIELD_27] [nvarchar](255) NULL
)
First of all, field names have been changed to protect the innocent. Second, I did *not* create this table...I'm troubleshooting issues with a previously created table. I've no idea why almost every field needs to be an NVARCHAR data type of that size. Finally, as you can probably guess, I'm getting this error on a SQL Server 2000 database. (Yeah, it's past time we upgraded to SQL Server 2005 at least...explain that to management, please. I suggest you speak slowly and use small words.)
Anyhow, the error is "Warning: The table 'ExampleTable' has been created but its maximum row size (13348) exceeds the maximum number of bytes per row (8060). INSERT or UPDATE of a row in this table will fail if the resulting row length exceeds 8060 bytes."
Am I misunderstanding how the row size is calculated? How is SQL Server getting 13,348 bytes from the above statement?
Any and all constructive suggestions/ideas are much appreciated! Thanks!

Temp Buffer Error Allocating ######## Bytes
Jan 11, 2008Hi Guys,
i've found many threds with SSIS buffer errors but non of them seems to work, or have a good solution. i'l explain the story short.
i've got a DB server running on Windows 2003 R2 Enterprise with 10GB RAM 20GB Virtual memory with same spec another machine for the web server.
both machines have "Lock Memory in memory" group policy enabled for
Network Service
System
DomainSQLServiceAccount (in DB server)
and in the DB memory "awe allocation" is also enabled.
both servers have /PAE /3GB switches enabled in boot.ini file
problem: i run all my SSIS packages in the web server through IIS. so the processes are devided between DB and web server. i.e SSIS service is also running in web server.
when i run packages under load (transforming - 200,000 records) i get buffer allocation errors.
A buffer failed while allocating 10485760 bytes.
Error Code = -1073450990
all packages i run i have set the default buffer temp to my web servers e: emp (got 260GB space left). and defaultbuffer size is 10mb with 10,000 defaultbuffermaxrows.
funny this is when it hit 8.33GB (approx 875 files) i get the above error message. it always seems to give me errors after 8.33GB.
Note: all packages run in IIS (w3wp.exe). i'm configuring my new production boxes. the old production with similar envirnment (less speed) work with the same data and packages fine under load.
new production machine got more memory than the old machine but i get memory error (buffer). it doesn't even use up all available physical memory, only about 3gb (max), then start buffering to disk.
any help would be greately appreciated.
i also got
The system reports 31 percent memory load. There are 10734981120 bytes of physical memory with 7326126080 bytes free. There are 3221094400 bytes of virtual memory with 283840512 bytes free. The paging file has 12661686272 bytes with 9633767424 bytes free.Error Code = -1073450991
this was before i increased virtual memory to 20gb(from 4gb).
Any ideas i can try out?
